Sith Master is a high rank. At this rank you are able to to have Apprentices. Activity is now no longer the only way to grow in rank. It's also demanded for a Sith Master to finish the training of one Apprentice in order to become a Sith Lord. Sith Masters are in the clan for a longer time and should be able to take some responsibility aswell.
Every member has the responsibility to assist officers/guild leaders in any aspect of guild business if required. In addition, members should use their own initiative and creativity as best they can to benefit the guild. If you have a useful idea for a project, do share it. There's a great chance we will approve, and may even provide you with resources (or even financing) to see that task completed.
